[dxf] Allow users to override the layer name to be exported to DXF

PR Description:

This PR makes it possible to override the output name of individual layers exported in the DXF Export dialog.

The corresponding processing algorithm's GUI and parameter were updated accordingly.

Tests were added for:

• Output layer name precedence for the exported DXF: 1) attribute, 2) layer title, 3) overridden layer name, 4) layer name.
• Processing qgsprocessingparameterdxflayers parameter and DXF layer's widget wrapper.
